Thanks for the summary, is really useful as I was recently looking
into code in that
area. One thing I was trying to understand is why ppc needs _IO_BASE
at all rather
than using the generic PCI_IOBASE? 

Perhaps because our code predates it ?  I haven't looked much into
the semantics of PCI_IOBASE yet...

Yes, I'm pretty sure that's all there is to it. PCI_IOBASE just
happened to be an identifier we picked for asm-generic, but the
use on PowerPC is much older than the generic file.
